And in the explanation of Allah the Exalted’s statement:“And they ask you about menstruation. Say: It is harm, so keep away from women during menstruation, and do not approach them until they are pure. Then when they have purified themselves, go to them as Allah has commanded you (i.e., intercourse in the front, not the back). Indeed, Allah loves those who repent and loves those who purify themselves.”And the statement of the Prophet (peace and blessings of Allah be upon him) that this is a matter which Allah has decreed for the daughters of Adam. Some of the people of knowledge have said that menstruation first appeared among the Children of Israel. Abu Abdullah (Imam Bukhari, may Allah have mercy on him) says that the hadith of the Prophet (peace and blessings of Allah be upon him) includes all women.

Narrated Al-Qasim: `Aisha said, "We set out with the sole intention of performing Hajj and when we reached Sarif, (a place six miles from Mecca) I got my menses. Allah's Apostle came to me while I was weeping. He said 'What is the matter with you? Have you got your menses?' I replied, 'Yes.' He said, 'This is a thing which Allah has ordained for the daughters of Adam. So do what all the pilgrims do with the exception of the Tawaf (Circumambulation) round the Ka`ba." `Aisha added, "Allah's Apostle sacrificed cows on behalf of his wives."

Narrated `Aisha: While in menses, I used to comb the hair of Allah's Apostle .

Narrated `Urwa: A person asked me, "Can a woman in menses serve me? And can a Junub woman come close to me?" I replied, "All this is easy for me. All of them can serve me, and there is no harm for any other person to do the same. `Aisha told me that she used to comb the hair of Allah's Apostle while she was in her menses, and he was in I`tikaf (in the mosque). He would bring his head near her in her room and she would comb his hair, while she used to be in her menses."

Abu Wa'il used to send his maidservant, while she was in the state of menstruation, to Abu Razin, and she would bring the Qur'an wrapped in a cover, carrying it with her hand from his place.

Narrated `Aisha: The Prophet used to lean on my lap and recite Qur'an while I was in menses.

Narrated Um Salama: While I was laying with the Prophet under a single woolen sheet, I got the menses. I slipped away and put on the clothes for menses. He said, "Have you got "Nifas" (menses)?" I replied, "Yes." He then called me and made me lie with him under the same sheet.

Narrated `Aisha: The Prophet and I used to take a bath from a single pot while we were Junub.

During the menses, he used to order me to put on an Izar (dress worn below the waist) and used to fondle me.

While in I`tikaf, he used to bring his head near me and I would wash it while I used to be in my periods (menses).
